PUMPING MECHANISM.

Specification of Letters Patent.

PatentedNov. 10, 1914.

Application filed October 13, 1913. Serial No. 794,955.

To all whom it may concern Be it known that I, CHARLES W. COLLINS, a citizen of the United States, residing at Tifiin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Pumping Mechanisms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in pumping mechanisms, and the object of the invention is, in part, to provide a device of this general character having novel and improved means whereby the mechanism is prevented from becoming inoperative through freezing; and, in part, to provide a device of this general character having means of a novel and improved character whereby the water to be conveyed or elevated by the mechanism is agitated in order to purify the same and whereby the walls of the cistern or the like from which the water is conveyed or elevated are washed.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous foruse, all as will be hereinafter more fully set forth. v

The novel features of the invention will be carefully defined in the appended claims. In order that my invention may be the better understood, 1 will now proceed to clescribe the same with reference to the accompanying drawings, wherein- Figure 1 1s a view partly in section and partly in elevation illustrating a pumplng mechanism constructed in accordance with my invention; and Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Asdisclosed in the accompanying drawings, 1 denotes a cistern, well or the likein which the water stands and 2 denotes a pump cylinder of predetermined length in which is suitably mounted for recurrent movement through the action of the operating member 3, the rod 4 having suitably secured at its lower end the piston 5 being herein shown as comprised of two concave cups, preferably of leather having their con- Ivex sides in contact thus making a double cup or solid piston.

lVhile the drawings disclose the operating member 3 for thepump in the nature of a hand operated lever, 1 do not wish to be to the specific means for operating the pump, as the means disclosed is only conventional tion to be employed in connection with a pump operated from a suitable source of power such as a windmill or other motor. Adjacent its upper end the cylinder2 provided with an air inlet 6 under control of of the cylinder 2 and preferably in the up per head thereof is provided a petcock 8 whereby the air pressure created within the cylinder above the piston 5 may be regu: lated. adjacent the lower portion thereof and beboth as the induction and eduction port for the cylinder, such pipe 9 being in communi- 1 or other source of water supply and to the discharge pipe 12, the flow through the pipe 10 being under control of the check valves 14 and 15 interposed therein at either side of the pipe 9 the check valve 14: preventing inward thrust of the piston 5, while the check valve 15 serves to prevent the admisoutward stroke of the piston 5 which stroke results through suction 1n the drawing of the water from the cistern 1 or other source which isbelicved to be obvious. I

The water pipe 11 is directed within the cistern 1 to a predetermined point below the water line therein and is in communication with the cylinder or enlarged portion 16 of the air line 17 which air line or pipe 17 is directed in such a manner as to communicate with the cylinder 2 at the upper portion thereof and above the piston 5. The lower portion of the water pipe 11 is provided posedtherein a check valve 19, the water within the cisternl being adapted to enter understood as limiting myself in any way as a the check valve 7 and in such upper portion In communication with the cylinder cation with the pipe 10 which leads to both the water pipe 1]. leading from the cistern:

back flow of the Water in the pipe 12 on the sion of air within the cylinder 2 upon the of supply Within the cylinderQ in a manner with a depending branch 18 having inter as it is the particular purpose of my invenlow the piston o is the pipe 9 which serves 1 within the water pipe 11 through the branch 18 upon the outward stroke of the piston 5, said check valve 19 serving to prevent the escape of air therethrough, as is believed to be obvious.

Upon the outward strokeof the piston 5,-

the air admitted within the cylinder 2 above the piston 5 through the air inlet 6 will be forced through the air line or pipe 17 and within the cylinder or enlarged portion .16 which is preferably of a diameter substantially equal to twice the diameter of the air line or pipe 17 and thus assist in theconveyance or elevation ofthe water within the water pipe 11 to within the cylinder 2 until the air reaches the vent 21 through which the air is discharged into the cistern thus agitating the water and serving to purify the water and clear it from insect life. As herein shown the vent comprises a pipe -member angularly directed from the pipe line 11 and rotatably supported thereby so that the resistance offered by the water to the escaping air will cause the vent pipe 21' to travel about the pipe 11 whereby an effective agitation of the water within the cistern is assured and this vent pipe 21 is of such a length as to'terminate in close prox imity to the wall of the cistern whereby the combined action of the air and water assures a washing of the cistern while it tendsto soften the water and produces a more sanitary condition. In order to increase the efliciency of the action of the air discharged, I find it best to provide at the free end of the vent pipe 21, the reticulated nozzle 22, as is water level in the well regardless of the pressure remaining 1n the air line. This is,

of particular advantage for assoon as the pumplng operation ceases, the water drops in the water line or pipe 11 to alevel, in that of the .air line or pipe 17 wherebythe cyl inder 2 is emptied of all water and thus preventing freezing therein and the. cistern-1 is of such a depth as to cause thewater level within the water line or pipe 11 and the .air

line or pipel'? to be at a point below the surface line as to thoroughly preventfreezing of the water therein.

While the petcock 8, hereinbefore referred to, may be properly adjusted to control the degree of pressure within the :air line, this pressure may be further regulated by the size of the openings in the reticulated nozzle 22. I also interpose in thewater pipe 11 just back of the check valve 14 a petcock 23 which upon being opened is adapted to facilitate the return of the water after the pumping operation to its level and also affords a coupling whereby air may be pumped for other purposes as it will be readily understood that when such petcock 23 .is opened, the suction created by the piston. 5 will have no effect upon the water within the cistern or well.

It is thought to be obvious that my improved pumping'mechanism is of such a character that should from any cause the suction fail to work that water may be elevated through the action of the air alone and should from any cause the air fail to work that the water may be elevated entirely by suction.

From the foregoing description it is thoughtto be obvious that a pumping mechanism constructed in accordancewith my in vention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which the water may be conveyed or elevated and of the certainty with which the water within the mechanism is safeguarded against freezing and it will also be obvious that my invention issusceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying outmy ini vention in practice.
